I'd love for Shulk to be in as well. I don't really know if it's unlikely for him to be in, because it doesn't seem to me that these characters get in through popularity or the quality of their design or anything like that. Sometimes it seems arbitrary.

For example, given the rising popularity of Monster Hunter in the west thanks to Nintendo, and the good relationship that Capcom and Nintendo seem to have going on, I would think that putting in a monster hunter in Smash is an obvious choice. But then, who really knows.
